Patented Sept. 20, 1949 CENTRIFUGAL SEPARATOR WITH MOV ABLY SUPPORTED SUPPLY CAN THERE- FOR William H. Harstick, Oak Park, and Otto E. Hintz, Jr., Chicago, Ill., assignors to International Harvester Company, a corporation of New Jersey Application June 24, 1946, Serial No. 678,864

6 Claims. 1

This invention relates to centrifugal separators and more particularly to cream separators.

More specifically, it relates to the supply can of a centrifugal cream separator. A supply can for cream separators is generally positioned above a cream separating bowl, and fluid to be treated is supplied to the bowl by means of a discharge nozzle projecting from the supply can. It becomes necessary at times to disassemble the cream separating bowl, and in so doing the bowl is generally removed from the remaining structure of the cream separator. Before removing the bowl it is generally necessary to remove the supply can or tankso that ready access may be had to the cover for the separating bowl, the bowl itself and its associated parts. This complete removal of the supply can has many disadvantages, for fluid may be contained within the can thereby making it awkward to handle, and it is generally diflicult to find a temporary storage place where the can may be free from possible contamination. Damage to the can due to handling is also a usual and undesirable result.

It is the prime object of this invention therefore to provide an improved supply can for a cream separator, said supply can being readily movable to a non-use position.

Another object is to provide a supply can which can be vertically raised from a use to a non-use position.

A still further object is to provide a supply can which can be readily moved to a non-use posi-' tion and rotated, thereby permitting ready access to a cream separating bowl and its associated parts.

Another object is to provide a foot operable means for raising a supply can of a type used with a centrifugal cream separator.

Other objects and advantages will become more readily apparent from a reading of the following description and accompanying drawing, in which:

Figure 1 is a side elevational view of a centrifugal cream separator having certain portions thereof broken away to better illustrate the invention;

Figure 2 is a plan view of the same; and

Figure 3 is a sectional view taken along the line 33 of Figure 1.

A centrifugal cream separator is generally indicated by the reference character "I. The cream separator l includes a housing structure II, fabricated in this instance from sheet metal, having at its bottom a base portion [2 to which are connected legs l3. Connected to the top portion of the sheet metal housing structure II is a closure member M. A member [5 is positioned below said closure member l4, this member acting as a stiffener and also providing means for supporting an electric motor or driving means, not shown. Supported on the closure member I4 is a stationary tin-ware construction which in-v cludes a milk-receiving container l6 having connected thereto a milk discharge spout l1. Positioned beneath the milk-receiving container I6 is a cream-collecting container I8 which has connected thereto a cream discharge spout 19. A separating bowl 20, as shown in dotted lines, is mounted for rotation underneath a bowl cover 2|.

Positioned above thev cream separating bowl 20 is a supply can 22. The supplyj'can 22 normally contains the liquid to be treated which is discharged from the can through a discharge nozzle 23 into the interior of the separating bowl 20. A valve handle 24 is adapted to regulate the discharge of liquid to be treated from the supply can. Rigidly connected to the underneath portion of the supply can is an annular collar 25 which is seated upon a supply can support generally designated by the numeral 25. The supply can support 26 includes a vertically extending tubular member 21 which is connected at its uppermost portion to a spider 28 having a plurality of supporting arms 29 which rigidly support the supply can 22.

The tubular member 21 extends downwardly through an opening 3| in the closure member l4 and through an opening 32 in the member l5, said closure member l4 and member l5 acting to serve as a guide and bearing means for the tubular member 21. The tubular member is provided at its bottom-most portion with a bearing member 33 rigidly held within the tubular end by means of a collar 34. The bearing member 33 is provided with an opening'35. A thrust member 36 is rigidly held within the opening 35, said thrust member extending through an opening 3'! formed in the base portion l2 and through an opening 38 formed in a horizontal section 39 of the leg I3. A lug 40 is rigidly connected to the side of the thrust member 36. This lug 40 cooperates with a slot 4! formed through the base member l2 and the horizontal section 39.

A treadle member 42 is pivotally connected, as indicated at 43, to the base portion I2 and to one of the legs l3. The treadle member 42 includes a pedal element 44 which is pivotally connected thereto as indicated at 45. A bearing pin 46 is connected to a portion of the treadle member 42, said bearing'pin acting to engage the thrust member 36. A locking or' latching hook 41 is connected to the pedal member '44 and is positioned to rotate with said member. This looking hook is adapted to engage a hook portion 48, as indicated generally in dotted lines in Figure 1. A set-screw ceus'fscrs ed thrcugI-i =tnemcrmcma1 section 39 and tl'irollgh the base per-non 42- to engage the lower surface of the bearing member 33. The setscrew 49 serves'to provide for vertical adjustment of the support 2611., I 1

When it is desired for any-'i-r'eiasdn torefiidv'e' the separating bowl or its associated parts, the

operator simply steps on the actuating the treadle to force tlie thfust member- 36 upwardly and thereby raise the supply can support 26 and the supply can 22; 'Thehook por tion 41 engages the hook portion 48 tohold the supply can in its elevated non u se' positibnt -'=I=he' supply can and supply can support are thereupon suppiiedto the separating bowl. Actuationof Y treadle, 'however', causes this lug A0 to be raised above the baseportion l2'so that His no longer in enga ementwith the opening 2 I, therepyp'ermittmg rotationbrtne supply can 28 and the Supply can '22 to its non-use position; By raisin'g'ftheflc an clearance between the bowl land the nozzle 23 is efie't'ed. When the can is turned ahu tnenozzle 23is shifted to the'broken line position 'ofFi'gure'ZQ the nozzle-is no longerin axial alinemeht with the bowL thereby providing ample clearanceto permit removal of the bowl.

It'i's'thus clearly apparent that the objects of theinvention have been fullyachieved, and it iriustbennders toodthat-various changes and modifications may be made which donot depart from the spirit of the invention asd-iselosedanor the scope of the appended claims.
